Fig. 9 is a detail view with some parts sectioned on the line 9 9 of Fig. 7; and

Fig. 10 is a view principally in vertical section, illustrating a modified form of the means for attaching the copy holder to a typewriter. Y

The copy holder includes an upright body described and of the copy 11 formed from a flat sheet of metal, the ver tical edge portions of which are turned back to afford reinforcing flanges 12 and 13, and the upper edge portion of which is turned back to afford a horizontal top shelf lll. This body 11 is rigidly secured to a base 15 formed from sheet metal, the edge portions of which are turned upward to afford reinforcing flanges, and which base extends forward of said body and is arranged to beinserted under the rear frame bar A of a typewriter B as shown in Fig. 3.

To detachably secure the copy holder to the typewriter B in working is pivoted to the back of the body 11, just above the base 15, apair of horizontally spaced vertically swinging arms 16 having laterally and forwardly projecting extensions 17, which work through apertures 18 in said body and arranged to be inserted under the `base bar A by a bodily movement of the copy position, there intermediately pivoted to the back of the body 11. This lever 2O is connected to the arms 16 by an upright rod 21, the upper end of which is attached to the short end of said lever, and the lower end is attached to the intermedia-te portion of an inverted V-shaped spring rod 22 the ends of which are attached to said arms. This rod 21, at its lower end portion, is guided by a keeper 23 pressed from the body 11. The lever 2O is adjustably held with certain of the notches 19 interlocled with the frame bar A, by a dog 24 formed therewith and co-operating ratchet teeth 25 formed with a segmental bar 26 on the back of the body 11,

For holding a copy sheet C there is provided a yieldingly held clamp in the form of a horizontal clamping bar 27 arranged to press the upper vend portion of said sheet against the face of said body near the top thereof. The upper edge of this clamping bar 27, at its intermediateportion, is formed with the outer face of the horizontal portion of an L-shaped body member 28 that extends through an oblong aperture 29 in the body 11 from the back of said body. The upper edge of the vertical portion 0f the clamping body 28 is shaped to form a pair of axially spaced spaced hinge lugs through which extends a hinge pin 3() mounted in a pair of ears 31 on the back of the bodyV 11. A coiled spring 32, encircling the hinge pin 30 between the hinge lugs on the body 28, has one of its ends in body and is under strain to yieldingly hold the clamping bar 27 inengagement with the race ol the body 11.

To hold a note book l) there is provided a horizontal retaining bar 33 located above the clan'iping bar 27 and laterally spaced in 'liront oit the body 11 with the end portions inset and secured to said body. This retaining bar 33 is adapted to -hold the note book l) at itsl bound end by inserting one el the covers between the body 11 and retaining bar 33 from the top thereof, as sb o wn in Fig. 7. The other cover the book l) and the leaves thereof as they are turned over the shell 14 are held by a weight 34. This weight 34 is carried by an arm hinged at 36 to said shclt above ythe flange 13 'ior vertical swinging*movement.

T he line guide includes a carriage 37 mounted lor sliding movement on the ange and having` yielding rictional j engage- .ment with the body 11 at the Ylace and back thereof. One end ot a horizontal main straight edge bar 38 is secured to the carriage and is held thereby parallel to the face of thebody l1 and spaced outward thereof for vertical movement over the copy sheet G or outer leal of the book D, as shown'in Fig. 7. A supplemental straight edge bar 39 has One of its ends pivoted to trie tree end of the main straight edge bar 38 for vertical swinging movement parallel thereto. llfhen the supplemental straight edge bar 39 is adjusted to term anv extension ol;l the main straight ec ge bar 38 the same is supported on a stop lug 40 on said main straight edge bar. A hooklike lug` 41 on the main straight edge bar 38 is provided to support the supplemental straight edge bar 39 when folded as shown in Fig. 1.

The 'following connections are provided for lowering the carriage 37 step by step to intermittently move the straight edge bar 38 from line to line over the 'face of the copy sheet C or outer leal ot the book l), to wit:

fr' gravity held dog42 is pivoted to the carriage 37 at the back thereof for co-operation with a ratchet bar 43 mounted for vertical endwise movement in upper and lower pairs et' bearingbrackets 44 on the inner tace ot the body flange 13.V This ratchet bar 43 is provided with a multiplicity of longitudinally spaced holes in any one of which the dog 42 will enter and interlock therewith during a downward movement ot' the bar 43 and secure the carriage 37 to said bar for common movement therewith. But during an upward movement of the ratchet bar 43 the dog 42 will move over said bar-with a ratchetlike action, thus permitting the carriage 37 to remain stationary. A stop plate 45 'on the lcarriaeeA 37 limits themovement of the doo D n into the holes in the ratchet bar 43, as

shown in Fig. 9. To manually release the bell crank 47 is mounted on a bearing on the lace ot the body 11 and its arm, to which the link 48 is attached, projects through an aperture in said body. The other' arm 01"' the bell crank 47 is attached to a rock shaft 49 by crank-acting arm 50 secured to said shalt. This rock shaft 49 vis journaled in bearings on the face ot the body 11 just above the base 15. To operate the rock shaft 49 there is applied tothe right-hand end thereoia long linger lever 51 that projects forward oi'the keyboard ot the typewriter B, as shown in F 3. This lever 51 is detachably .gplied to the rock shaft 49 by providing the same with a laterally proj ccting sleeve that is detachably tclescoped onto therespective end o1 said rock shalt and vhas angular' interlocking engagement therewith for common rocking movement. A. coiled spring 53 anchored to the body 11 and attached to the bell crank 47 at the link 48 is under strain to yieldingly hold the rat'chet'bar 43 with its upper end in engagement with the shella 14 as a stop, and also returns the lever 51, bell crank 47, link 48 and ratchet bar 43 to normal positions alt-er being operated.

To cause the carriage 37 to move predetermined steps or downward movement and thereby intermittentlyset the main straight edge bar 38 for single, double or triple spacing, there isprovided selective stops 54, 55 and 56 :tor the bell crank 47. Thcs stops 54, 55

and-.'56 are in the form of circumterentially spaced lingers formed with a vdisc 57 pivoted to the back ot the body 11 for oscillatory n'iovement. A linger lever 58 for oscillating the disc 57 is connected theretoby a long rod 59. This linger lever 58 is pivoted to the back ot the body 11 withvitstree end extending through a slot in the body flange 12. For trictionally holding the lever 58 in different positions, a coiled spring 60 is compressed between said lever and its head and yieldingly presses the same against'the back of the body 11, as shown in Fig. 8.

The modication shown in Fig. 10 illustrates avery simple device for attaching a copy holder'to-a typewriter and comprises a pair ot soar springsl anchored by encircling a horizontal rod 61 secured to the back ot a holder body 62 with one ofv their ends engaging saidback as a base of resistance and their other ends having horizontal arm extensions 63 which project throughV apertures in said back and having a plurality of notches 64 arranged to interlock with the lower edge of the ramebar E of said typewriter. To attach the holder to a typewriter by means of these arms'63 itis only necessary to spring the same downward under the bar E and then release the same to cause the notches 64 to intypewriter or released therefrom.

terlock with said bar.

The operation of the copy holder may be briefly described as follows:

Obviously, by manipulating the lever 20 the holder can be very quickly attacheld to a o secure the copy sheet C to the holder it is only necessary for the operator to insert one of his fingers under the clamping bar 27 through a finger notch 29 in the body 1l and draw the clamping bar 27 away from said body to permit the copy sheet C to be inserted thereunder. Upon releasing' the clamping bar 27 the spring 32 will return the bar to an operative position and Vhold the copy sheet. If notes are to be transcribed from the book D the same will be attached to the holder by the retaining bar 33, as previously described. The upturned end of the weight 34 makes it easy to engage the same to lift the weight and thereby insert one of the leaves of the book thereunder.

To move the straight edge bar 38 downward over the face of the copy sheet C or outer leaf of the book D and stop the same at the desired line, the lever 58 is first operated to position one of the stops 54, 55 or 56 under the bell crank 47, depending on the spacing of the lines, whether it is single, double or triple. To shift the straight edge bar 38 to the next line below it is only necessary for the operator to depress the lever 5l and thereby cause the crank arm to move the bell crank 47 and draw the ratchet bar 43 downward unt-il engaged by the positioned stop 54, or 56. Upon releasing the lever 51 the spring 53 will immediately reset the ratchet bar 43 without moving the carriage 37. At the completion of the upward movement of the ratchet bar 43 the dog 42 will again reenter one of the holes in said ratchet bar. The purpose of the supplemental straight edge bar 39 is to form an extension of the straight edge bar 38 when a wide copy sheet is attached to the holder.

For variable or irregulark spacing, the stop 56 may be adjusted under the bell crank 47 for triple spacing and the operator by manipulating the finger lever 4l by slight touches can work the straight edge bar 38 down .to the desired position. It is, therefore, evident that this device is capable of use either for positive or for variable spacing. In fact, the stops act positively only in one direction, so that any line feed movement less than that for which the stop is set to operate may be produced Simply by pressing the lever downward a distance less than that required to bring the stop into action. F or variable or irregular spacing, it is advisable to set the stop for three-space maximum movement.

lVhat we claim is:

In a holder of the kind described, the combination with a body, of a straight-edge bar movably mounted on the body, operating means for imparting steps of movement to the straight-edge bar, a member mounted to turn about a fixed axis and having a plurality of circumferentially spaced radially extended stops located different distances from the axis of said member, an operating lever, and a link connecting said lever to a crank eXtension on said member for operating the same to position said member with any one of the stops for the operating means to vary the length of the steps of movement of the straight-edge bar for predetermined different line spacing.

In testimony whereof we afliX our signatures.
